Shocking online non existent. Almost like it's a ****

I cannot for the life of me, believe how bad Zara online is. It was the first time I ordered from Zara online and it's been the absolute biggest mistake of all time. And I ordered 4 dresses, that I wanted for my holiday and I leave next week. There is NO number to call, and they reply HOURS later on the Instagram post etc and I think it's a robot. There is absolutely NO way to get through to them and, I cannot track my order. I've been begging to simply collect my order, so that I have it on time. We can't even find my order number but there is proof of payment and a thing showing it's being prepared. Without the order number they can't help me!!!!!!. Please don't do it. Never, ever again. All i want now is a refund and they can keep the clothes
